横断面

First , a reevaluation of published epidemiologic studies of consumption of sweetened beverages and overweight shows that most such studies either are cross-sectional or are based on passive surveillance of temporal trends and thus permit no conclusions about causal links . Second , research evidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusive .

第一，已出版的关于含糖饮料摄入与肥胖的流行病学研究重新评定表明：大多数这种研究要么是横断面调查要么是基于目前这种趋势的一种被动性的监测，因而研究也存在着允许两者因果关系不成立情况；第二，关于不同类型饮料和固体食物短期内谁更能使人觉得饱胀能力的比较调查还没有结果。

Second, research eidence comparing the short-term satiating power of different types of liquids and of solids remains inconclusie. Numerous clinical studies hae shown that sugar-containing liquids, when consumed in place of usual meals, can lead to a significant and sustained weight loss.

It was discovered that reinforced embankments had overturn trends after watered and the trends aggravated when the geogrid space was reduced or the slope was steepened, while slope of the embankment without geogrid was failure in the same conditions.

获得了土工格栅加筋路堤横断面位移分布和路堤中土工格栅应变随时间变化的情况，发现在边坡坡脚浸水的情况下，加筋模型有绕边坡坡脚倾覆的趋势，倾覆趋势随加筋密度的增大和边坡坡度的增大而增大，而不加筋路堤边坡发生了滑塌，表明土工格栅的加入提高了路堤的整体性。

布莱希特戏剧虽然截取的是一个个生活横断面，但并没有完全突破时间顺序的顺延发展，仍有贯穿始终的情节线存在和主要人物性格的逻辑发展。

It shows that the average thickness of the surface layer of crystals,the palisade and cone layer and the eggshell membrane are 20.8,220.8 and 62.5μm,respectively,which accounting for 6.8%,72.6% and 20.6% of the total thickness of the eggshell.There are many vesicular holes in palisade layer with an average diameter of(0.32±0.08)μm(n=30).The function of such holes may be of significant to air exchange.The shape of eggshell pore on the surface layer of crystals is round or ellipsis.The fracture surface of the pore is funnel-shaped.

结果表明：白冠长尾雉卵壳的表面晶体层、栅栏锥体层和壳膜层的厚度分别为20.8，220.8和62.5μm，分别占卵壳总厚度的6.8%，72.6%和20.6%；栅栏层有很多蜂窝小孔，其直径为(0.32±0.08)μm(n=30)；卵壳表面有许多圆形或椭圆形的气孔，可能与胚胎发育过程中的气体交换有关，气孔横断面呈细漏斗状，在其上半部有颗粒状填充物。

An 1-D sediment mathematic model is developed in the second part. Techniques are suggested for some problems in calculations, such as the effective suspended load carrying capacity of the different bed material reach, the coefficient of suspended load carrying capacity, the recovering coefficient of the carrying capacity, the thickness of the mixed layer, the transport width of the bedload, bifurcation and confluence of main and branch channel, and the distribution of deposition and erosion along the cross section, etc. The numerical scheme of 1-D model is induced.

第二部分建立了一维泥沙数学模型，对计算中的几个关键问题提出了处理方法，如不同床沙组成河段的有效挟沙力、挟沙力系数、挟沙力的恢复饱和系数、床面混合层厚度、推移质输移带宽度、干支流入汇及分流问题、横断面冲淤形态及断面修正方法，导出了一维模型的差分格式。
